Megan Smith, now the nation’s chief technology officer, and Mikey Dickerson, U.S. digital service administrator, held meetings with their old running mates at Google less than a month after moving over to the White House. Smith met 10 times with Google employees, in total, while Dickerson held five meetings with his former colleagues.

Alex McGillivray, deputy chief technology officer, and Nicole Wong, former deputy chief technology officer, also each had one meeting with Google employees.

All four worked for Google immediately before moving into government work at 1600 Pennsylvania Avenue. The timing of their meetings raises questions about a policy Obama implemented a day after taking office.

“I will not for a period of 2 years from the date of my appointment participate in any particular matter involving specific parties that is directly and substantially related to my former employer or former clients, including regulations and contracts.”

While each executive agency appointee must sign an ethics pledge, the “Executive Order allows for a waiver when the literal application of the Pledge does not make sense or is not in the public interest,” the White House website says. The site lists the people on that list, but Smith, McGillivray, Dickerson and Wong are not on it.

While White House visitor logs show that those onetime Google employees met with former colleagues, they do not reveal the substance of the conversations.

Obama’s White House door has certainly proven to be open to Google. As Watchdog.org previously reported, company officials have visited the White House an average of more than once a week since Obama took office. And there are more than 250 instances of Google employees going to work for the federal government or vice versa during that span.

Campaign for Accountability, which is compiling the Google Transparency Project, said the meetings between ex-Googlers and their former colleagues “raise questions about President Obama’s commitment to keep business interests from exercising undue influence on his administration.”

Silicon Beat, the tech blog of the the San Jose Mercury News, reported in July that Campaign for Accountability is part of the New Venture Fund, which is heavily funded by the Bill & Melinda Gates Foundation and the Flora Hewlett Foundation. Silicon Beat also reported “there’s nothing to suggest either the Gates or Hewlett foundations had any knowledge that their beneficiary was attacking Google.”

The White House media affairs office didn’t return Watchdog.org’s call seeking comment on the meetings between ex-Google employees and their former colleagues. Google, through a spokesperson, declined to comment.

This isn’t the first time the Google-White House connection has been ethically questioned.
